Abstract Text - FPAR (2) :

CONSTITUTION: As for the microprogram, the
micro- instruction is read out to
the micro- instruction register 3 from the
control memory by the (n) bit of the
address stored in the micro- instruction
address register 2 . Also at the same
time, the decode mode is read out to the
decode mode register 6 from the decode
mode memory by use of the high rank (a) bit of
the address stored in the
register 2 . The decoder 4 decodes the
micro- instruction stored in the
micro-instruction register 3, and modifies the
decode output prescribed by the
decode mode which has been stored in the
register 6.
